1、获取 Nginx 状态（ HTTP Stub Status ）
|
1
|
/usr/local/nginx/sbin/nginx
-V
|
2、配置 nginx.conf
|

|
vim
/usr/local/nginx/conf/nginx
.conf
location ~
/nginx_status
{
stub_status on;
access_log off;
allow 127.0.0.1;
allow 192.168.1.14;
deny all;
}
|
3、编写脚本获取上面的 key 值

vim
/script/nginx_status
.sh
#!/bin/bash
case
$1
in
active)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'/Active/ {print $3}'
;;
accepts)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'NR==3 {print $1}'
;;
handled)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'NR==3 {print $2}'
;;
requests)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'NR==3 {print $3}'
;;
reading)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'/Reading/ {print $2}'
;;
writing)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'/Writing/ {print $4}'
;;
waiting)
curl -s http:
//127
.0.0.1
/nginx_status
|
awk
'/Waiting/ {print $6}'
;;
*)
echo
"Usage: $0 { active | accepts | handled | requests | reading | writing | waiting }"
;;
esac
chmod
a+x
/script/nginx_status
.sh
|
4、添加自定义 key 配置文件

vim
/usr/local/zabbix/etc/zabbix_agentd
.conf.d
/nginx_status
.conf
# Nginx_status
UserParameter=nginx.active,
/script/nginx_status
.sh active
UserParameter=nginx.accepts,
/script/nginx_status
.sh accepts
UserParameter=nginx.handled,
/script/nginx_status
.sh handled
UserParameter=nginx.requests,
/script/nginx_status
.sh requests
UserParameter=nginx.reading,
/script/nginx_status
.sh reading
UserParameter=nginx.writing,
/script/nginx_status
.sh writing
UserParameter=nginx.waiting,
/script/nginx_status
.sh waiting
5、修改zabbix_agentd.conf
vim
/usr/local/zabbix/etc/zabbix_agentd
.conf
LogFile=
/tmp/zabbix_agentd
.log
Server=192.168.1.14
ServerActive=192.168.1.14
Hostname=Zabbix server
Include=
/usr/local/zabbix/etc/zabbix_agentd
.conf.d/
EnableRemoteCommands=1
UnsafeUserParameters=1
|
6、Zabbix 服务端测试能否拿到 Key
|
1
|
/usr/local/zabbix/bin/zabbix_get
-s 192.168.1.12 -k nginx.active
|
Nginx 监控项解释
Active connections: 1
server accepts handled requests
1 1 1
Reading: 0 Writing: 1 Waiting: 0
## Active connections: 对后端发起的活动连接数
## Server accepts handled requests: Nginx 总共处理了 1 个连接，成功创建了 1 次握手（没有失败次数），总共处理了 1 个请求
## Reading: Nginx 读取到客户端的 Header 信息数
## Writing: Nginx 返回给客户端的 Header 信息数
## Waiting: 开启 keep-alive 的情况下，这个值等于 active - ( reading + writing ), 意思是 Nginx 已经处理完成，正在等待下一次请求指令的驻留连接
## 在访问效率很高，请求很快被处理完毕的情况下，Waiting 数比较多是正常的。如果 reading + writing 数较多，则说明并发访问量很大，正在处理过程中
